Abstract
The present invention is a device for measuring the intensity of the light scattered by a thin film of a colloidal medium, comprising a monochromatic light source, a convergent optical system focusing the source onto the thin film to be analyzed comprising a dioptric element with one of the faces thereof constituting a first wall defining the thin film, at least one photosensitive detector producing a signal representing light scattered or backscattered by the thin film and means for processing the signal. A second wall of the device has a plane surface at the end of a rod.
